Merge tag 'pci-v3.15-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas:
"These are fixes for an SHPCHP hotplug regression, a "wait for pending
transaction" problem (used in device reset paths), and an email
address update.
PCI device hotplug:
- Fix SHPCHP bus speed mismatch issue (Marcel Apfelbaum)
Miscellaneous:
- Fix pci_wait_for_pending_transaction() (Gavin Shan)
- Update email address (Ben Hutchings)"
* tag 'pci-v3.15-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
PCI: Wrong register used to check pending traffic
PCI: shpchp: Check bridge's secondary (not primary) bus speed
PCI: Update my email address
